Einstein's Field Equations
http://en.wikipedia.org/wiki/Einstein_field_equations

The Einstein field equations (EFE) or Einstein's equations are a set of ten equations in Einstein's theory of general relativity which describe the fundamental interaction of gravitation as a result of spacetime being curved by matter and energy.[1] First published by Einstein in 1915[2] as a tensor equation, the EFE equate spacetime curvature (expressed by the Einstein tensor) with the energy and momentum within that spacetime (expressed by the stress-energy tensor).
Similar to the way that electromagnetic fields are determined using charges and currents via Maxwell's equations, the EFE are used to determine the spacetime geometry resulting from the presence of mass-energy and linear momentum, that is, they determine the metric tensor of spacetime for a given arrangement of stress-energy in the spacetime. The relationship between the metric tensor and the Einstein tensor allows the EFE to be written as a set of non-linear partial differential equations when used in this way. The solutions of the EFE are the components of the metric tensor. The inertial trajectories of particles and radiation (geodesics) in the resulting geometry are then calculated using the geodesic equation.
As well as obeying local energy-momentum conservation, the EFE reduce to Newton's law of gravitation where the gravitational field is weak.

from the answers that I've recieved, MANY OF THEM WRONG, apparently, I'm not the only person who didn't exactly know he answer. Many things that are fundamental get lost, it happens all the time. I misunderstood that concept, not exactly in the way that some that have come here and thought, but I did. I'm sure you have that misunderstanding about something that I may consider ridiculous. Oh well, I now have a slightly better understanding.

Don't know much about Galaxies...oops. In 4th grade, and basic school in general, I only remember discussing the Solar System. When you discuss stars at the same time, it would seem that they are a part of it.


Exile, I aint even mad atcha. I guess in some ironic way the "simple" question you asked brought out a lot of complex and convoluted bullshit answers. LOL.
And you're right. The fundamentals do get lost admist the complicated jargon.

Occam's Razor. All the great scientific minds were aware of this precept.

But hey, now you have a better undertanding and that's all that counts. I always tell my student, "a stupid question is the one you never asked"

Gravity isn't even completely understood. There are many theories that describe the nature of gravity, it's a question of compatability. The quest for the most fundamental is still ongoing.

Well, I'm glad we're getting into this shit to answer a dude who didn't know that universes weren't inside galaxies. (No offense to the OP)

You can always tell the difference between those that want to help, and those that are jumping up and down, pissing in their pants to show how much they know. So you know the difference between Eisteinian and Newtonian physics. Great. Good for you. Now how does that help the OP?

ScorpDiesel and 4ce of N8ture, y'all are muddying up the waters, and neither of you is adding anything useful to the thread.

The OP got his answer, correct? Yup, I was pissin' my pants to show what I know. LOL Weren't u doing similar by exposing ur "inner geek"? I digress...

I hurt this nigga 4ce of FAIL's man-feelings. So, now he types in all caps & bold to compensate for his diminutive ego & knowledge. I'll let him get all his pain & frustrations out by playing his game. It's the least I can do. Notice he STILL hasn't found info to confirm what he's saying.

Newton and his collegue Roger Cotes were taking a walk talking about physics and astronomy, got carried away in a deep philosophical debate, forgot that it was getting late and decided to pitch a tent and continue the conversation. Fell asleep and Newton wakes up in the middle of the night:

Newton: "oh fuck, Roger wake up! Look up! See!??"
Cotes: "Ah yes, Orion's belt! Quite a spectacle of a constellation ..."
Newton: "No you idiot! They've stolen our tent!!"

The difference between trying to help and pulling the shit you were is that I actually answered the questions the OP (and other people) were asking. You're just getting into a pissing contest with 4ce to show off how much better your google skills are than his. I've read everything you've posted, and so far I haven't seen a single thing that actually helped the thread along. :smh:

thanks, that's it. I know it's a simplistic question, but the fundamentals are where everything gets all jacked up. So the Milky way is the center of our galaxy, which contains multiple universes?

No the universe is all that it encompasses. Everything that is in the universe IS the universe. Stars, gasses, planets, matter/anti-matter... THAT is the universe. The Milky Way isthe galaxy in which we reside in and is just one galaxy that has many solar systems and stars that all circle around an extremely powerful point of gravitational pull. Usually a black hole (I could be wrong in this but a black hole is the strongest form of gravity in which not even light can escape). We are not at the center of our galaxy. From what scientists have gathered, we are at the edge of one of the arms of the the Milky Way galaxy. No where near the center. In short, multiple galaxies (and even the stray stars gasses, and what not) make up the universe.

So, it's justified if ur helpin'? Actually, u weren't helpin'. The Star Trek quadrants u mentioned with ur "inner geek" have nothing to do with the OP's question, does it? I support my comments with info from other websites in the same way u posted pics to support Star Trek claims. So again, how is what u do different?

I get that. I know the sun is a star. But the earth only orbits the sun, as I assume all the other stars are, but if I'm correct, some stars out there are even bigger than the sun,some that we can see under certain conditions. If they all orbit the sun, then I assume they all stay in a fixed place because of their orbits.

I knew I'd get clowned for it, but whatever. :lol:

You know there is more than one galaxy right? Ours is one of millions...:lol::lol::lol:

Yes, it's different to try and help a man with a question by giving an answer. That's not what you were doing.

And the Star Wars/Star Trek stuff was in answer to another question. So far I've answered 2 questions, while you've answered 0. Some people just like to hear themselves talk. Before this thread I never thought that was you.

The "stars" you see are soooo far apart there is no chance in hell they will ever collide. When I say far apart I mean it takes light years to get from one to another. The sun is a "star" it is much closer but light still takes 7-8 minutes to get to earth which is considered pretty close to the sun. Even the other planets are extremly far from each other as in millions and millions of miles apart even though they go around the same sun.

Some of the stars you see from other solar systems are 10,000 light years from earth meaning it takes light ten THOUSAND years just to get here. In other words there is NO CHANCE any of those stars will EVER hit any other star that is actually in our solar system. Just to put this all into perspective the visible universe is estimated to be 14 billion light year across so the universe is so vast and matter is sooo spread out such collisions you speak of just do not happen very ofter as in almost never.


The sun is one of a billion suns in our milky way galaxy. Only 8-9 planets orbit our sun. There are ONE BILLION other planets out there and they orbit other objects like our sun. For you to understand this you must understand that our sun is not unique. There are millions of other "suns" out there that have planets like earth around them and they are far far away.

I get that- I think where I fucked up is the fact that the other stars aren't in our solar system at all. The sun is the closest star to us, which is why we orbit the sun. The sun, and all other stars orbit whatever the center of our galaxy is called. So yeah, Gravity puts it all in a fixed pattern, but I was wrong well ahead of that :lol:

You seem to have learned a lot here. The center of the Milky Way, our galaxy is called Sagitarius A. It is a SUPERMASSIVE blackhole. This black hole is so powerful it holds all of the matter in our galaxy together the way our sun holds our planets in an orbit.

Speaking of collisions, our Milkyway galaxy will one day, a long long time from now, crash into the Adromeda Galaxy. This collisioin may send our sun and the earth into deep space out of the galaxy all together. It will be the biggest collision in this region of the universe since the big bang according to astronomers.

You actually did a pretty impressive thing here. While logically considering what you thought you were taught, you realized that the facts didn't add up. It took man hundreds of years to start questioning the heliocentric model of the universe. Call it an inductive leap or independent thought, but questioning what you have been taught like that is a sign of higher intelligence in my book. Posting on bgol... Well there may have been better ways to research ur answer, but you knew it'd be good for a laugh and someone else might have the same question or answer.

Hell when I was a kid I thought that buck rogers was flying through stars at the end of the show, and wondered why so many small stars collided like that.

that what makes me keep coming here. I love looking at pussy like the next man, but it's hilarious to know that there are some extremely intelligent dudes on here, if you ask the right line of questions. I've clowned plenty of dudes on here for their question, so I just took my knocks. The problem I was having in thinking about it is, I couldn't figure out what it was I really wanted to know, so I didn't know where to start looking :lol: I do now, thanks to the PORN BOARD.:lol::lol:

I aint trippin on getting clowned, I know I aint stupid.

i'm not sure what you're asking.

gravity is a relationship between two objects with mass - according to the equations. therefore you have a relationship to the earth a gravitational relationship - and that relationship is governed primarily by two things - size and proximity. the bigger the thing - the more the gravity. the closer you are to it - the more it affects you.

so earth's gravity acts singularly on you and affects your behavior. you jump up - earht pulls you back down, etc.

the earth's relationship to the sun is like a ball on a string. spin around and let the ball swing in a circle around you at the end of a string - and this is what you have - gravity is that invisible string. the orbit is balanced by gravitational pull on one side and centripetal momentum on the other - producing a stable orbit.

i think this is right anyway. i'm no astronomer.

Mass, not size.

that's pretty much what I was asking, and I get that part. I see that the earth ad other planets are fixed in their orbits because of it. And I suppose the stars are as well so they must be fixed as well. Thanks.

Basically that's true, but relativisticly speaking the planets are not on a fixed orbit. As stars like the Sun age their mass changes which in in turn affects the planets' orbit. The same goes for stars and galaxies. They are not in a fixed position because the universe is constantly expanding. we can't detect sigificant changes since it takes billions of years and we are talking about distances usually measured in millions of lights years.

You should check out the Universe on the History Channel. It's on at 6 p.m. EST today. You can watch How The Earth was Made. It's on the History Channel right now. This might give you an idea of the concept of things.

Exactly. What you described is called cosmic red-out.

But this all depends on whether dark energy maintains the acceleration of cosmic expansion.

Other predictions are that the acceleration stops and the universe expands for ever or the acceleration get even faster and dark energy basically rips apart everything, galaxies, superclusters and even atoms or it decelerates and and collapses to an eventual popular big crunch theen another big bang and the cycle continues.

Funny thing about all of this is that the stars, planets and us make up less than 0.5% of the universe so will we really wont be missed.

See, this is the problem with googling answers. Everything you said is 100% correct. Unfortunately it has NOTHING AT ALL IN ANY WAY to do with the post you quoted. NO-THING. What you copied has to do with our current theory as to the end of the universe. Dude was talking about when our galaxy collides with the Andromeda galaxy. :smh:
